As summer temperatures soar globally, markets such as Europe and Southeast Asia are experiencing a new wave of demand for heat-relief products. This issue focuses on the "Sleep Cooling" trend. By analyzing the latest data from platforms like Amazon, TikTok Shop, Shopee, Lazada, and Google Trends, we break down four major hot categories—cooling blankets, cooling bedding, cooling pillows, and cooling mattress toppers—into 12 high-potential subcategories, helping sellers capture the European summer consumer window.

1. Category Background

Keywords like Cooling Blanket, Cooling Bedding, and Cooling Pillow have hit peak search volume on Google Trends. On TikTok, #CoolingBlanket, #HotSleeper, and #SleepTok continue to gain traction, with creators driving product awareness through "real sleep tests" and "heat challenges." Meanwhile, during the Amazon Prime Day warm-up period, these cooling products consistently rank in summer home bestseller lists. Notably, Bedsure's cooling blanket sold over 6,000 units in the past 30 days, becoming an iconic hit this summer.

· Product Selection Rhythm

Jul–Aug: Peak demand as heat intensifies; highest order volume of the year.

Aug–Sep: Back-to-school season in Europe drives demand from students and renters.

Post-Sep: Markets gradually shift to all-season sleep products, extending to long-tail categories like bamboo bedding and breathable mattress pads.

· Cooling Bedding Trends & Selling Points

Trend 1: Sleep Cooling becomes a new consumer hotspot. In 2026, consumers increasingly seek ways to "stay cool all night without AC." Data shows rising interest in "Hot Sleeper" and "Night Sweat" as entry points for product marketing.

Trend 2: Tech cooling fabrics are core hit features. Beyond traditional ice silk or bamboo, consumers now value Q-Max cooling value, Arc-Chill fibers, PCM phase-change materials, and breathable quick-dry fabrics. OEKO-TEX certification, machine washability, dual-sided designs, and eco-friendly materials are key purchasing factors.
